Reticular shadows

Reticular interstitial pattern is one of the patterns of linear opacification in the lung. It can either mean a plain film or HRCT/CT feature.

Pathology

Causes

Reticulation can be subdivided by the size of the intervening pulmonary lucency into fine, medium and coarse. Diseases with a predominantly reticular pattern can be subdivided by the acuteness of their presentation.

• predominantly reticular: acute, not a common pattern
  • pulmonary edema
    • heart failure
    • fluid overload
    • nephropathy
  • infection
    • viral
    • mycoplasma
    • Pneumocystis
    • malaria
  • drug reactions
• predominantly reticular: chronic
  • post-infectious scarring
    • tuberculosis (post-primary)
    • histoplasmosis (chronic)
    • coccidioidomycosis (chronic)
    • Pneumocystis
  • chronic interstitial edema
  • mitral valve disease
  • collagen vascular disorders
    • dermatomyositis/polymyositis
    • ankylosing spondylitis
    • mixed connective tissue disease
  • rheumatoid lung
  • scleroderma
• idiopathic pulmonary hemorrhage
• granulomatous disease
  • pulmonary sarcoidosis
  • eosinophilic granuloma
• pulmonary neoplasms
  • lymphangitis carcinomatosis
  • pulmonary lymphoma and other lymphocytic disorders
  • lymphocytic interstitial pneumonitis
• inhalational lung disease
  • asbestosis
  • silicosis
  • coal workers pneumoconiosis
  • hypersensitivity pneumonitis (chronic phase)
  • chronic aspiration pneumonia
• drug reactions
  • nitrofurantoin related lung changes
  • chemotherapeutic agents
  • amiodarone lung toxicity
  • radiation pneumonitis
• idiopathic
  • usual interstitial pneumonia
  • lymphangioleiomyomatosis
  • tuberous sclerosis
  • neurofibromatosis
  • amyloidosis
